Hi,
does anybody have an idea what to do if ICH6 BIOS Lock is enabled and BIOS Write is disabled? Removing the lock bit seems to fail according to flashrom.

my idea was to use dmidecode that i can get informations like that:
Handle 0x0100 DMI type 1, 25 bytes. System Information Manufacturer: Dell Inc. Product Name: OptiPlex GX280 Version: Not Specified
Sometimes dmidecode also has information on BIOS size. Having that info as well would be nice.
Handle 0x0000 DMI type 0, 20 bytes. BIOS Information Vendor: Dell Inc. ROM Size: 512 kB
If there are machines where flashrom does not find a flash chip, please run flashrom -V.

Thanks.
Found chipset "Intel ICH6/ICH6R", enabling flash write... BIOS Lock Enable: enabled, BIOS Write Enable: disabled, BIOS_CNTL is 0x2 tried to set 0xdc to 0x3 on Intel ICH6/ICH6R failed (WARNING ONLY) FAILED!
Dell has locked the BIOS against writing. We try to unlock it, but we fail.
Does the BIOS have any settings like "BIOS/Flash write protection" or something similar?
note: please understand that i have no intention to run ./flashrom -w before i am totaly sure that i can revert that.
OK. Good decision.
